Fig. 2 — Predicted number of children (y-axis) by country-level variables (x-axis) and woman’s educational level with 95 % confidence level intervals for pair-wise comparisons. Note: Predictions are obtained using estimates from multilevel Poisson’s regression models (Models 1–6, Table 4). Values of country-level variables are ranged over the observed ranged of values. Confidence intervals are centered on the predictions and have lengths equals to 2 × 1.39 × standard errors to have an average level of 5 % for the Type I error probability in the pair-wise comparisons of a group of means (Goldstein and Healy 1995)
